Abstract

Verfahren zur Bestimmung der Amplitude und/oder der Phase des Stromes am Ausgang eines insbesondere durch einen Synchronmotor belasteten PWM-Umrichterkreises, der einen vor einem Wechselrichter liegenden Gleichstromkreis aufweist, wobei der Wechselrichter mindestens zwei Schalter aufweist, die in geschlossener Schaltphase den Strom auf eine Ausgangsleitung durchschalten, aufweisend folgende Schritte:
  • Der Strom im Gleichstromkreis wird über einen mehrere Schaltphasen umfassenden Zeitraum gemessen und registriert.
  • Aus dem registrierten Stromverlauf, insbesondere aus der Änderung des Stromes zwischen den Schaltphasen, wird eine Verlaufscharakteristik abgeleitet.
  • Aus der Verlaufscharakteristik wird eine Korrelationsfunktion ermittelt, über die der Strom am Ausgang bestimmbar ist.
